Description

  It relates to a V-belt angle measurement jig used to measure the side angle of a V-belt, and it is very easy to use with a CMM without using the belt as a measurement sample. The present invention relates to a jig that can be measured.

  As a conventional method for measuring the side angle of the V-belt, for example, there is a method of measuring using a projector as shown in Patent Document 1, and a cut sample is created to measure the belt, and the angle is measured by projecting a cross-sectional shape. It was a method of measuring.

  However, in the case of a V-belt in which a plurality of resin blocks are mounted on a center belt as shown in Patent Document 2, the angle can be measured using a projector if the block is a single unit before being assembled to the center belt. However, when the block is attached to the center belt, the angle of the block changes due to the occurrence of a slight deflection.

  In measuring the angle with the projector, the belt must be cut, for example, a sampling inspection of the manufactured belt can be performed with the projector, but a total inspection is not performed.

  Also, in the case of a belt with multiple blocks attached to the center belt, the side angle of the block after the change must be measured with the center belt attached, and the method using a projector measures the angle. I can't.

  The present invention improves such a problem, and a V-belt angle measuring jig that can measure the angle of the side surface of the belt very easily using a three-dimensional measuring machine without cutting the V-belt. For the purpose of provision.

  That is, according to the invention described in claim 1 of the present application, it is a jig for measuring the side angle of the V-belt with a three-dimensional measuring machine, and is fixedly arranged so as not to move the measuring side of the endless V-belt. It is characterized by having a measuring table and a receiving portion for storing a side not used for measurement.

  According to a second aspect of the present invention, the V-belt angle measuring jig has a configuration in which the measuring table is attached to the support table via the leg part, and the V-belt angle measuring tool uses the space between the support unit and the measuring table as the storage unit. It is a jig.

  According to a third aspect of the present invention, there is provided a V-belt angle measuring jig in which the support base, the leg portion, and the measurement base are arranged so as to have a substantially U-shaped cross section, and an accommodating portion surrounded by them is formed.

  According to the first aspect of the present invention, there is provided a measuring table for fixing and arranging the side used for the measurement of the V-belt, and a housing part for housing the side not used for the measurement of the belt, and even an endless belt is cut for measurement. In this state, the angle can be measured by fixing it to the V-belt angle measuring jig.

  In Claim 2 and Claim 3, it is set as the structure which connects a support stand and a measurement stand by a leg part, and provides an accommodating part between both stand, and the side which is not used for the measurement of a belt is stored in this accommodating part. Since the belt on the side used for measurement can be fixed to the measuring table and placed on the measuring unit of the coordinate measuring machine, the angle of the V belt can be measured without taking time and effort.

  According to the fourth aspect, the V-belt can be firmly fixed to the measuring table of the jig, and a more accurate angle measurement can be performed.

  1 is a cross-sectional view of a V-belt angle measuring jig according to the present invention in which a belt to be measured is mounted, and FIG. 2 is a cross-sectional view taken along line AA in FIG. This V-belt angle measuring jig 1 is a substantially U-shaped member. In an endless belt, a support base 2 for placing the jig 1 underneath and stabilizing it is positioned above and used for measurement. The measuring table 3 which fixes and arranges the side to be used is connected with the leg part 4, and the receiving part 5 is surrounded by the supporting table 2, the measuring table 3 and the leg part 4.

  A fixture 6 that can be moved up and down in the direction of the arrow by loosening the bolt 6a is attached to the measurement table 3 so that the V belt 7 can be fixed. Fix with the fixture 6 so that it does not move.

  The shape of the V-belt angle measuring jig 1 is not limited to the substantially U-shape shown in FIGS. 1 and 2. A U-shaped measuring jig or a substantially U-shaped measuring jig in which the vicinity of the center of the support table 2 and the end of the measuring table 3 are connected by the leg 4 may be used.

  A procedure for measuring the belt side surface angle using the V belt angle measuring jig 1 will be described below. The end 7 of the V-belt 7 to be measured is placed on the measuring table 3 of the measuring jig 1, and the side not used for measurement opposite to the belt is housed in the housing 5, and the belt 7 is held by the fixture 6. Fix to the measuring table 3. Further, it is also possible to change the place where the belt is measured by rotating the V-belt as necessary. When the belt 7 is attached to the V-belt angle measuring jig 1 and set in the measuring unit of the coordinate measuring machine 8, and when the measurement is started, a plurality of positions on the belt side surface are measured by the measuring terminal 9, and the obtained plural The angle of the belt side surface is calculated from the position data.

  Thus, it is not necessary to cut the endless belt for measurement, and the measurement work can be completed with a very simple work by using the V-belt angle measuring jig 1 of the present invention.

It is a front view of the place where the belt is attached to the jig for measuring the V-belt angle of the present invention. It is AA sectional drawing in FIG. It is a front view of the place which is measuring the angle with a coordinate measuring machine.
